13 CONFIGURATION OF CPUM / IOCN CARDS
Jumpers on the CPUM and IOCN cards are used to configure the external communications
interfaces.
Refer also to the block diagrams in 6 CPUM / IOCN card pair (Figures 6-1, 6-2, 6-3 and 6-4).
NOTE: The location of the jumpers on the CPUM card can be found using Figure 13-16 or
Figure 13-17.
The location of the jumpers on the IOCN card can be found using Figure 13-18.
13.1Configuring Ethernet communications
Primary Ethernet communications can be routed via either the ‘NET’ connector on the CPUM
card’s panel or the ‘1’ connector on the IOCN card’s panel.
The choice is made using jumpers J42, J40, J52 and J53 on the CPUM card.
The location of the jumpers on the CPUM card can be found using Figure 13-16 or
Figure 13-17.
(b) The 1 Ethernet connector on panel of IOCN is selected
